What Is the Memory Capacity of a Developmentally Delayed Squirrel?
The question that you may be asking yourself is, what is the memory capacity of a developmental-delayed squirrel? It is important to keep several factors in mind while answering this question. For instance, if a squirrel is unable to remember details, he is not able to solve a problem in the same way that a normal squirrel would. In that case, the problem-solving capability of a squirrel may be very low, but he may not know where to look for things in the environment.
Problem-solving ability of a developmental delayed squirrel
A new study has uncovered some intriguing findings about the problem-solving abilities of a developmental delayed squirrel. Researchers measured the number of times the squirrels touched a lever with any part of their body. Squirrels typically used their nose and teeth to touch the levers. On subsequent trials, they moved onto a new lever and counted their attempts. The researchers were able to deduce that squirrels who made a variety of attempts used either a generalisation search or an exhaustive one.
Genetics and neuroendocrine factors are involved, as is the environment in which we live. Complex interactions with other animals likely influence problem-solving ability, and it is expected to change as we age and are exposed to new environments. This is why problem-solving is a highly evolved skill. The study suggests that it is a phylogenetic trait, and the ability may have evolved from a common gene pool.
Searching for alternative solutions to solve a familiar but different problem
In this study, we found that the developmentally delayed squirrels were capable of solving a modified version of a familiar but unfamiliar problem. The squirrels exhibited high tendencies to pull, which may be a generalisation of a previous successful solution. These squirrels also showed high levels of inhibitory control, but they did not exhibit a persistent preference for pushing. These findings suggest that squirrels used a ‘backup’ solution after failing in the original problem. We believe that this ‘backup’ solution search is a form of generalisation, involving retrieving related information and applying it to the modified problem.
The search for alternate solutions to a familiar but unfamiliar problem is a crucial aspect of successful problem-solving. The conditioned response to a previous solution is called proactive interference, and the squirrels emitted one or two ineffective pushing behaviours for every successful behavior. The result of this behaviour is that the squirrel soon realises that the previous solution is not effective and uses a more preferred solution.
Attention to relevant task information
The development of attention to relevant task information is a common trait of a wide range of animals, including humans. Unlike humans, animals with developmental delays show a higher tendency to generalise previous successful experiences and to use inhibitory control when faced with new ones. Our findings indicate that attention to relevant task information may contribute to problem-solving efficiency and may explain the contrasting responses of developmental delayed and able squirrels.
Our study showed that Eastern grey squirrels were flexible in their problem-solving strategies, with the tendency to abandon their preferred solution and attempt alternative solutions. These behavioural strategies often involve a trial-and-error method to access a rewarding reward, and may also involve a backup solution if the first one failed. Therefore, we conclude that attention to relevant task information in a developmental delayed squirrel is an important feature of the brain that is not evident to all individuals.
Pulling the far-end solution
The University of Exeter scientists discovered that grey squirrels remember a task they were given 22 months ago. Using a new, redesigned test, they learned the skills quickly. This discovery could help the grey squirrel survive in cities, where bird feeders are a common source of food. They learned the new task in just two seconds compared to eight seconds the first time around. The results have many implications for wildlife conservation.
